I followed OVM User's Guide for Release 3.2 Beta to Chapter 8.10.10 to Move one Virtual Machine To Unassigned Virtual Machine folder after shutting down the VM but failed with below error, could somebody help?

"8.3.1. Virtual Machines Using Resources in an OCFS2 Repository Cannot be Migrated To The Unassigned Virtual Machines Folder

Any virtual machine which has resources in ocfs2 repository cannot be migrated to Unassigned Virtual Machines folder, the only exception is if the ownership of this OCFS2 repository has already been released. "

If the repo of a VM is OCFS2 (then that VM uses "OCFS2"), then in 3.2+ you can no longer move it to the Unassigned VM Folder. Instead you can drag that VM to the "Server pool" and thereby it is no longer assigned to any server, it is assigned to the server pool itself instead.

If this is not enough, you could open an Enhancement Request and specify the needs.
